Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a range hood which is installed above a gas stove or a gas stove in a kitchen and discharges oil smoke, odor, etc. generated during cooking to the outside.

[0002]

[Prior Art]

 The range hood installed above the kitchen gas stove, gas range, etc. is equipped with a fan unit inside the box-shaped hood body with an open bottom surface, and the oil smoke drawn into the hood body by the operation of the blower unit, It discharges odors etc. to the outside through an exhaust duct connected to the hood body.

Further, the range hood described above is installed at a position at a safe predetermined height that is not affected by the flame or heat generated from a heating cooker such as a gas stove or a gas stove, and moreover, a hood that houses a blower unit. The main body is a box-shaped body with an open lower surface that integrates the four sides of the back, left and right sides, and the front.

[0004]

[Problems to be solved by the device]

 Therefore, there is a considerable space between the upper surface of the cooking utensil and the lower end of the range hood, and the oil smoke, odors, etc. generated during cooking spread before reaching the range hood and are collected and exhausted by the range hood. However, there is a problem that it drifts around the range hood, and there is a problem in the collection effect. As a method to solve such problems, it is possible to lower the installation position of the range hood and bring it closer to the cooking utensil, but in that case, the front plate of the range hood interferes with the cooking work on the cooking utensil. There are problems such as difficulty.

Further, in recent years, cooking using edible oil has increased due to westernization of eating habits, etc., and along with this, oil stains around the range due to scattering of oil droplets have become a problem, and in order to prevent the oil stains. Conventionally, a commercially available guard that covers the sides and back of the stove is used exclusively, but due to the storage when not in use, etc., there is a limit to the size (height) of the oil drop. It is difficult to say that it is possible to effectively prevent oil stains due to the limited range of scattering prevention.

The present invention has been made in view of the problems of the above-mentioned conventional techniques, and the purpose thereof is to have an excellent collection effect and an oil droplet scattering prevention effect, and make cooking work inconvenient. It is to provide a range hood that does not.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the range hood in the present invention has a blower unit mounted inside the hood body, and between the blower unit and the peripheral wall of the hood body, the back and left and right sides are three sides or the left and right sides are two sides. It is characterized in that the rear hood and the front hood are made of slidable up and down and that the front hood and the rear hood are independently slidable up and down by dedicated ascending / descending motors.

The operation of the lifting motor for vertically sliding the rear hood mounted inside the hood body is controlled by the various sensors such as an ultraviolet sensor, a temperature sensor, or a gas sensor to control whether the range is used or not. A method of detecting and judging and controlling by the detection signal, or operating buttons for operating and stopping each motor are installed on the surface of the hood main body or the front hood, and the operating buttons are operated manually to operate the motors. The method of controlling the stop can be appropriately selected. In addition, the operation of the lifting motor that slides the front hood up and down is controlled by a human sensor or distance sensor that detects whether the user is in front of the hood or the cooking device. A method of controlling with a signal can be used.

[0009]

[Action]

 According to the above-mentioned means, the front hood and the rear hood are lowered to a predetermined position by interlocking with the use of a heating cooker such as a gas stove or a gas stove or by a manual operation of an operation button or the like. The lowered front hood and rear hood are effectively collected before the oil smoke, odors, etc. rising from the cooking utensil spread to the surroundings. Moreover, since the front hood and the rear hood slide up and down independently of each other, the rear hood can be lowered to a position in contact with the upper surface of the cooking device because the rear hood does not disturb the cooking operation, and the front hood can be used for cooking work. Since it is easy to get in the way, it can be adjusted separately to a position where it does not interfere with cooking.

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a hood body, which is formed in a cylindrical shape with an open lower surface, and a blower unit 2 is provided on an inner surface of a top plate 1a of the hood body 1. The fan unit 2 is suspended and fixed, and the exhaust port of the blower unit 2 is connected to the duct connection port of the top plate 1a and connected to the exhaust duct 3 outside the hood body 1. A rear hood 4 and a front hood 5 are vertically slidably housed between the blower unit 2 and the peripheral wall of the hood body 1 inside the hood body 1.

The blower unit 2 which is suspended and fixed in the hood body 1 is a well-known one which is constituted by a casing 6, a fan 7 and a motor 8, and the blower unit 2 is a casing in which the back and left and right sides are surrounded by a flat plate. It is housed in a case 10 having a filter 9 attached to the front surface facing the suction port (bell mouth) of 6, and the case 10 is also fixed to the top plate 1a of the hood body 1. The filter 9 mounted on the front surface of the case 10 may be fixed to the case 10 itself, but by making it removable from the front surface of the case 10, cleaning and replacement of the filter can be easily performed. Can be done.

The rear hood 4 mounted between the peripheral wall of the hood body 1 and the case 10 is formed in a substantially U-shape in a plan view in which the back surface and the left and right sides are surrounded by flat plates. The upper portion is supported between the peripheral wall of the hood body 1 and the case 10 by being engaged with a rectangular hanging frame 12 which moves up and down by the driving of a lifting motor 11.

A suspension frame 12 that suspends and supports the rear hood 4 is a rectangular frame body that surrounds the outer periphery of the case 10, and a receiver 13 is fixed to the outer surface of the frame side facing the back plate of the hood body 1. The receiving members 13 are engaged with the guide rails 14 provided on the back plate of the hood body 1, so that they can be slid vertically from the upper part to the lower part in the hood body 1. The suspension frame 12 has one end of a wire 15 connected to the left and right sides of the frame, and the other end of the wire 15 is connected to a pulley 16 rotated by a lifting motor 11. As a result, the suspension frame 12 is supported so as to move up and down by the drive of the lifting motor 11. The lifting motor 11 is constituted by a motor that rotates in the forward and reverse directions.

The front hood 5 is formed in a substantially U-shape in a plane surrounding the front ends of the left and right sides of the rear hood 4 and the front surface of the hood body 1 as described above. The receivers 17 are fixed to the outer surface of the upper part, and these receivers 17 are engaged with the guide rails 18 provided on the inner surfaces of the front plate and the left and right side plates of the hood body 1, whereby the upper part to the lower part of the hood body 1 are It is arranged to be slidable vertically. One end of a wire 19 is connected to the upper part of the front hood 5, and the other end of the wire 19 is connected to a pulley 21 rotated by a lifting motor 20, which is driven by the lifting motor 20. It is designed to go up and down. Further, the left and right rear end portions of the front hood 5 are overlapped with the left and right front end portions of the rear hood 4 to form a rectangular enclosure with the front hood 5 and the rear hood 4. Is done.

Further, a switch box 21 is sectioned and formed in a lower portion of the front wall of the front hood 5 described above, and a board of switches for operating the blower unit 2 described above is operated in the box. In addition to being housed, the operation buttons 22 and the human sensor 25 are provided on the surface of the front wall, and the human sensor 25 has the user (cook) in front of the range hood or the cooking device. Whether or not the presence of the user is detected, the front hood 5 is lowered to a predetermined position, and when the presence of the user is detected, it is moved up and down to the original position. To control. Further, an ultraviolet sensor 23 is attached to the rear surface of the switch box 21. This ultraviolet sensor 23 detects the ultraviolet rays radiated from the flame when a gas stove of the cooking utensil 24 is ignited and a flame is emitted, and determines whether the cooking utensil 24 is being used (ignited) or not. It is a judgment.

The detection signal of the ultraviolet sensor 23 described above controls the operation and stop of the lifting motor 11 that moves the rear hood 4 up and down, and the ultraviolet sensor 23 detects the ultraviolet light emitted from the flame accompanying the ignition of the stove. Upon detection, the lifting motor 11 operates and the rear hood 4 is lowered to a predetermined position. Then, as a control method for raising the lowered rear hood 4 to the original position, there is a control method as shown in FIG.

The control method shown in FIG. 4 is a method in which the rotation of the lifting motor 11 is reversely rotated when the detection signal of ultraviolet rays from the ultraviolet sensor 23 disappears, and the rear hood 4 is automatically raised, A method in which a delay circuit is added and the elevating motor 11 is actuated to elevate the rear hood 4 after a lapse of a certain time from the absence of a detection signal, and a manual operation off switch is added to the control method described above. By manually operating the, the lifting motor 11 rotates in the reverse direction to raise the rear hood 4. If an off switch for manual operation is added, the lifting motor can be operated even if there is no detection signal from the ultraviolet sensor.

The above-described vertical sliding of the front hood 5 is not limited to the method of controlling the rotation direction of the lifting motor 20 by the detection signal of the human sensor 25 attached to the hood 5, and the operation can be performed. Of course, a method of manually operating the button may be used.

In the range hood configured as described above, when the ignition switch or the like is operated to ignite in order to use the cooking utensil 24, a flame is emitted accordingly, and the ultraviolet rays emitted from the flame are on the range hood side. It is detected by an ultraviolet sensor 23 provided on the rear hood 4, and the raising / lowering motor 11 is operated by the detection signal to lower the rear hood 4 to a predetermined position. As a result, oil smoke, odor, etc. generated by cooking are collected in the rear hood 4 before being diffused to the surroundings, and the collecting effect is improved. The reason is that the oil smoke generated by cooking diffuses to the surroundings as it goes away from the source, but rises almost straight up near the source, so the rear hood 4 that collects within the range that rises straight up 4 By locating, the leakage of collection can be reduced. When the detection signal of the ultraviolet sensor 23 is used as a control signal for operating and stopping the blower unit 2, the blower unit 2 is automatically operated at the same time as the rear hood 4 is lowered. The problem of forgetting to operate the blower unit 2 can be solved. Further, the lowering of the rear hood 4 described above can be expected to have an effect of preventing the scattering of the frying oil in the cooking of the tempura, in addition to improving the effect of collecting oil smoke, odor and the like.

When the user leaves the front of the cooking utensil (or range hood) after igniting the range of the cooking utensil, etc., the human sensor 25 provided in the front hood 5 stays within a predetermined range. Detecting the absence of a person, the detection signal activates the lifting motor 20 that slides up and down the front hood 5, and the front hood 5 descends to a preset position to produce oil smoke generated by cooking. It is possible to enhance the effect of collecting odors and the like. When the user stands in front of the cooking utensil again, the human sensor 25 detects the presence of a person and causes the lifting motor 20 to rotate in the reverse direction, whereby the wire 19 that suspends the front hood 5 is wound up. Then, the front hood 5 is raised to its original position. The vertical movement of the front hood 5 may not be controlled by the detection signal of the sensor, but may be moved up and down to an optimum position by manual operation of the operation button.

[0021]

[Effect of the device]

 Since the range hood of the present invention is configured as described above in detail, when the heating and adjusting device is used, the front hood and the rear hood descend to a position close to the top surface of the cooking device, and the oil smoke generated by cooking is increased. In addition, it is possible to efficiently collect odors and the like before diffusing them and prevent oil droplets from scattering around. Also, since the front hood and the rear hood slide up and down independently of each other, only the front hood should be used when looking at the food on the cooking utensil or operating the cooking utensil such as a pan. Can be raised to a position that does not interfere with work. Therefore, it is possible to provide a range hood which has an excellent collection effect, can eliminate the inconvenience of cooking work, and is highly usable.
